Question

A cylindrical specimen made of annealed 4135 steel has a diameter of 16 cm and is 12 cm high. It is upset, at room temperature, by open-die forging with flat dies to a height of 4.5 cm. Assuming that the coefficient of friction is 0.23, calculate the upsetting force (forging force) required at the end of the stroke. Take material properties, K=1015 MPa, n=0.17.

 

A cylindrical specimen made of
annealed 4135 steel has a diameter of
16 cm and is 12 cm high. It is upset, at
room temperature, by open-die
forging with flat dies to a height of 4.5
cm. Assuming that the coefficient of
friction is O.23, calculate the upsetting
force (forging force) required at the
end of the stroke. Take material
properties, K=1015 MPa, n=0.17.
Ffg = 84.4 MN
Ffg = 82.3 MN
Ffg = 81.1 MN
Ffg = 83.2 MN
